Problem with Cybergate RAT

Recently I learnt about the use RATS for hacking and learnt using CYBERGATE RAT. I followed what the tutorial said like making an account on no-ip.com etc. I forwarded the port and did literally everything. I tested the RAT on myself and it worked. Next day when I started voth no-ip and CYBERGATE up, no remote server was found. I made a new server and it didn't work as well. SInce then, I've port forwarded like a hundred times but the remote server doesn't show up. Please help me!!!
